FILTER-SPINNING AND SIMILAR MACHINE.

Application filed. July 16, 1926, Serial No. 122,967, and in Great Britain October 12, 1925.

This invention relates to flier-spinning and similar machines, especially to the wharles thereof, and it has for its object to afford greater freedom to the yarns or 5 threads in their passage to the fliers, which feature is especially advantageous in con nection with the spinning of lustrous fibres and the like.

According to the invention a wharle for a flier-spinning and similar machine is constructed internally with a downwardly flaring surface whereof the inclination is such that the yarn or thread extending from the pot-eye to and through the wharle is entirely unobstructed until it takes on to the flier leg.

The wharle may be formed with a downwardly depending neck in which the spindle is retained frictionally or otherwise and on to which the flier is screwed or is otherwise suitably secured.

The wharle may also be supported by means of a ball bearing whereof the outer race is carried by a sleeve retained in an overhead rail and whereof the inner race is mounted in a bush which constitutes the interior surface of the wharle and may be of substantially frustro-conical internal configuration; the internal inclination or form of the aforesaid bush being such that from the rim of the pot-eye to the lower edge of the wharle the yarn or thread can take a straight-line course without interference of any kind.

Instead of retaining a number of wharles in a continuous overhead rail each wharle may be fixed to an independent adjustable bracket. Also, instead of inserting a bush into the interior of the wharle the latter may be die cast to the appropriate shape.

One convenient form of the invention is illustrated by way of example, in sectional elevation, in the accompanying drawing in which the flierand the spindle are broken away at the lower end.

The wharle 1 is formed with a downwardly depending neck 2 slotted transversely at 3 below which slot the spindle 4: is fitted frictionally into the neck 2.

The flier 5 is screwed on to the threaded extremity of the neck 2 and abuts against a shoulder formed thereon.

6 is a bush which constitutes the interior surface of the wharle and which is pressed thereinto and is formed internally with a substantially frustro-conical or downwardly flaring surface terminating at the flared inner edge of the wharle.

The wharle 1 is supported in an overhead rail 7 by means of a ball bearing 8 whereof the outer race 9 is carried by a flanged sleeve 10 wherein it is retained by a locking ring 11, the sleeve being secured in an aperture in the rail 7 by a flanged cap or nut 12 screwing into the. sleeve. The inner race 13 of the ball bearing 8 is shrunk on to the neck 14 of the bush 6 and is clamped thereon by a lock-nut 15 screwing on to said neck 14.

16 is a pot-eye, of porcelain or the like, fixed eccentrically in the nut or cap 12, and 17 is an oiling passage formed in the rail '7. 18 represents the path of the thread through the pot-eye 16 to the flier 5.

It will be observed that by means of this similarly construction the distance between the poteye 16 and the neck of the flier 5 is considerably reduced, and also that the internal clearance of the wharle is such that the path 18 of the yarn from the rim of the pot-eye 16 to the flared lower edge of the wharle 1 is straight and completely unobstructed, both of which features are desirable and advantageous especially when spinning lustrous fibres and the like.

We claim:

1. Spindle-driving means for flier-spinning and similar machines, comprising, an overhead support, a wharle mounted rotatably in said overhead support, a spindle connected to said wharle, a flier connected to said wharle, and said wharle being con structed internally with a downwardly flaring surface whereof the inclination is such that the wharle presents interiorly an unobstructed passage for thread to pass to said flier without touching said wharle.

2. Spindle-driving means for flier-spinning and similar machines, comprising, an overhead support, a wharle mounted rotatably on ball bearings in said overhead support, a spindle connected to said wharle, a flier connected to said wharle, and said wharle being constructed internally with a substantially frustro-conical surface to form an unobstructed passage for thread to pass to said flier without touching said wharle.

8. Spindle-driving means for flier-spinning and similar machines, comprising, an overhead support, a wharle mounted rotatably on ball bearings in said overhead support, a spindle connected to said wharle, a flier connected to said wharle, a pot-eye located on said overhead support, and said Wharle being constructed internally With a substantially frustro-conical surface to form an unobstructed passage for thread to pass from said pot-eye to said flier Without touching said Wharle.

4. Spindle-driving means for flier-spinning and similar machines, comprising, an overhead support, a Wharle mounted rotatably on ball hearings in said overhead support, a downwardly depending neck having a bore on said Wharle a spindle received in the bore of said neck, a flier received on the exterior of said neck, a stationary pot-eye located above said wharle, and said Wharle being constructed internally with a substantially frustro-conical surface to form an unobstructed passage for thread to pass from said stationary pot-eye to said flier Without touching said Wharle.

5. Spindle'driving means for flier-spinning and similar machines, including a wharle characterized by a downwardly flaring internal surface whereof the inclination is such that thread can have an unobstructed passage therethrough Without touching said
